Abstract

Die vorliegende Erfindung bezieht sich auf ein Schachtkraftwerk (1) zur Stromerzeugung durch Energieumwandlung eines Abflusses zwischen Oberwasser (2) und Unterwasser (6), umfassend einen vertikalen Schacht (7), dessen Schachtkrone (10) eine Einlaufebene (11) bildet, welche unterhalb des Wasserstandes (3) des Oberwassers verläuft, wobei der Schacht (7) nach oben offen ist und an seinem unteren Ende mit einem Boden (9) verschlossen ist, eine Einheit (15) aus einer Turbine (16) und einer elektrischen Maschine (17), wobei die Einheit (15) komplett unter Wasser im Schacht (7) angeordnet ist, und wobei die Turbine (16) zum vertikalen oder geneigten oder horizontalen Wasserdurchlauf angeordnet ist, einen an die Turbine (16) angeschlossenen Ablauf (24), welcher einen geschlossenen Strömungskanal darstellt und durch einen Durchlass (28) im Schacht (7) zum Unterwasser (6) führt, und zumindest eine verschließbare Schachtspülöffnung (75) im Schacht (7) auf einer turbinenzugewandten Seite eines Rechens (21), wobei die Schachtspülöffnung (75) unter Umgehung der Turbine (16) zum Unterwasser führt (6).

Figure imgaf001
The present invention relates to a shaft power plant (1) for power generation by energy conversion of an outflow between the upper water (2) and underwater (6), comprising a vertical shaft (7) whose shaft crown (10) forms an inlet plane (11) below the water level (3) of the upper water, wherein the shaft (7) is open at the top and at its lower end with a bottom (9) is closed, a unit (15) of a turbine (16) and an electric machine (17 ), wherein the unit (15) is arranged completely under water in the shaft (7), and wherein the turbine (16) is arranged for vertical or inclined or horizontal water passage, a to the turbine (16) connected to the outlet (24) represents a closed flow channel and through a passage (28) in the shaft (7) leads to the underwater (6), and at least one closable shaft scavenging port (75) in the shaft (7) on a turbine-facing side ei of the rake (21), whereby the shaft scavenging port (75) leads to the underwater, bypassing the turbine (16) (6).
